Profile Summary: Itzhak Grinboim (aka broadcastNinja)

Itzhak Grinboim, better known in chess circles as broadcastNinja, is a force to be reckoned with on the digital 64-square battlefield. With a penchant for rapid tactical assaults and a bullet rating that once soared over 2300, Itzhak’s style is a fascinating blend of calculated precision and pure blitzkrieg.

Rating & Performance

Rising from a modest 1314 bullet rating in early 2019 to a peak of 2338 in October 2024, Itzhak’s progression is nothing short of impressive. Not to brag, but maintaining an undefeated streak of 7 consecutive wins at the start of his bullet journey shows early hints of greatness—and probably some lucky blunders from opponents.

His blitz skills are no joke either, peaking at 2213 in mid-2022, and his rapid chess play has reached nearly 2000. The one-day (daily) chess rating may be the most chill at 1847, but that’s the sort of patience you need to survive the marathon of life.

Playing Style

Itzhak is an endgame enthusiast, with a 74% tendency to fight it out in the long haul after the pieces start disappearing. He favors long battles, with an average victory unfolding across about 65 moves—so don’t expect quick wins unless he’s absolutely furious. His early resignation rate hovers at a respectful 17%, meaning he’s stubborn enough to stay in the fight, yet wise enough not to throw away the game on a whim.

One of his secret weapons is a remarkable 67% comeback rate, proving that when things get tough, broadcastNinja does not just fold — he folds, unfolds, and checkmates. But beware: his tilt factor is at 13, which in chess terms means he might throw some epic puzzles at you if you push his buttons hard enough.

Opening Favorites & Secrets

• The mysterious "Top Secret" opening line (not literally Top Secret, or is it?) shows a solid 50% win rate across nearly 2,300 bullet games.
• The King's Fianchetto Opening is a personal favorite with a 57.5% bullet win rate, indicating a love for both castle-ing and stylish piece posting.
• Not afraid to dive into the Old Benoni Defense, although the win rate dips to 39.3%, which might explain why that one is used sparingly—in the spirit of adventure.
• In blitz, broadcastNinja enjoys shaking things up with the Top Secret and Queen’s Pawn Opening (Horwitz Defense).

Noteworthy Achievements

- Holds a staggering 13 moves long winning streak, proving he can find the perfect storm.
- Has mastered the art of winning even after losing critical pieces, with a near 48% success rate.
- Demonstrates a strong psychological resilience, with a rated vs casual performance difference that simply means “don’t underestimate me” at all times.
- When the clock strikes 8 AM, that’s when Itzhak’s brain lights up — his best time of day for victories.

A Glimpse Into Recent Battles

On June 3, 2025, Itzhak (broadcastNinja) delivered a delightful checkmate victory over Raulito51 in a Closed Sicilian Defense—no doubt leaving the audience impressed with a long-fought game that showcased deep strategic understanding and impeccable timing.

Another recent highlight was his mastery in a swift blitz win against totoro44 featuring a King's Fianchetto Opening, concluding the game with decisive precision and grace.

A Chess Personality

If chess had a rockstar, Itzhak would be the headliner with a twist of ninja mystery. His username broadcastNinja truly encapsulates his lightning-fast moves and sometimes stealthy tactics that catch opponents off guard. Fun fact: He once won numerous games by checkmating opponents who barely knew what hit them—so if you’re facing him, keep your wits sharp and your pieces sharper.

Whether you’re an opponent, a spectator, or just a fan of the 64 squares, Itzhak Grinboim proves that dedication, resilience, and a touch of humor can carve a legendary path through the chess universe.
